Muva nje, ukutholwa komfutho wemisebe ezindaweni eziphila kuzo nasezindaweni zamanzi sekuphenduke isihloko esikhathaza kakhulu.Ukusabela kulesi sidingo, i-DWIN ithuthukise ngokukhethekile futhi yaklama isixazululo somtshina wemisebe esisekelwe kuzikrini ezihlakaniphile ze-T5L_COF, futhi ivule umthombo womklamo ukuze abasebenzisi babhekisele kuwo.
Ividiyo
1. Isimiso sokutholwa
Ikhawunta ye-Geiger iyithuluzi lokubala elithola ngokuqondile ukushuba kwemisebe ye-ionizing (izinhlayiya, izinhlayiya ze-b, ama-g ray nama-c ray).I-tube egcwele igesi noma igumbi elincane lisetshenziswa njenge-probe.Lapho i-voltage esetshenziswa ku-probe ifinyelela ebangeni elithile, umsebe ufakwa nge-ionized kushubhu ukuze ukhiqize ipheya lama-ion.Ngalesi sikhathi, i-pulse kagesi yosayizi ofanayo iyakhuliswa futhi ingarekhodwa idivayisi ye-elekthronikhi exhunyiwe.Ngakho, inani lemisebe ngesikhathi seyunithi liyalinganiswa.Kulolu hlelo, ikhawunta ye-Geiger ikhethwa ukuze kutholwe ukushuba kwemisebe yento eqondiwe.

Isithombe esingenhla sibonisa amapharamitha okusebenza ahambisana namamodeli ahlukene.Lesi sixazululo somthombo ovulekile sisebenzisa i-J305.Kungabonakala ngesibalo ukuthi i-voltage yayo yokusebenza ingu-360 ~ 440V, futhi amandla okunikezwa kwamandla anikezwa ibhethri ye-lithium evamile engu-3.6V, ngakho-ke i-boost circuit idinga ukuklanywa.
2. Isimiso sokubala
Ngemuva kokuthi ikhawunta ye-Geiger isisebenza ngokujwayelekile, lapho imisebe idlula kwikhawunta ye-Geiger, kukhiqizwa umshini wokushaya kagesi ohambisanayo, ongatholwa ngokuphazanyiswa kwangaphandle kwe-chip ye-T5L, ngaleyo ndlela kutholwe inani lama-pulses, abese eguqulwa abe yi-chip. iyunithi yokulinganisa edingekayo ngokusebenzisa ifomula yokubala.
Uma sicabanga ukuthi isikhathi sesampula siyiminithi elingu-1, ukuzwela kokulinganisa kungu-210 CPM/uSv/hr, inombolo ye-pulse elinganisiwe ngu-M, futhi iyunithi evame ukusetshenziswa yokulinganisa ukuqina kwemisebe ngu-Sv/hr, ngakho-ke inani okudingeka silibonise ngu-K. = M/210 uSv/hr.
3. Isifunda se-voltage ephezulu
Ibhethri le-3.6V Li-ion likhushulelwa ku-5V ukuze linikeze amandla esikrinini se-COF, bese isikrini se-COF se-PWM sikhipha igagasi lesikwele elingu-10KHz ngomjikelezo wokusebenza ongu-50%, oshayela i-inductor DC/DC boost kanye ne-back-voltage. amasekethe ukuze uthole i-400V DC ukuze icheme ukunikezwa kwamandla kushubhu ye-Geiger.
